How do I convert AAC to MP3 on Mac?
Open Picmal, drag your AAC files into the window, choose MP3 as the output format, set your quality, and click Convert.
Can I batch convert multiple AAC files at once?
Yes. Drag in as many AAC files (or a whole folder) as you like and Picmal converts them all to MP3 in one pass.
Does converting AAC to MP3 lose quality?
MP3 is lossy, and re-encoding from another lossy format can lose a little quality. Choosing a high bitrate (256–320 kbps) keeps it transparent for everyday listening.
